Tunnel type multi-layer microwave dryer is a device that uses microwave energy to quickly dry materials. This device has the advantages of fast drying speed, high efficiency, and low pollution, and is widely used in industries such as chemical, food, and pharmaceutical.
During the operation of the tunnel type microwave dryer, microwaves are first generated by a microwave generator and input into the microwave heater through an energy feeding device; The material is sent to the heater by the transmission system, and at this time, the moisture in the material is heated and evaporated under the action of microwave energy. Water vapor is removed through a dehumidification system to achieve the purpose of drying. The bacteria in the material are killed by the biological and thermal effects generated by the microwave electromagnetic field. Due to the direct action of microwaves on materials, the drying temperature is low and the speed is fast, resulting in minimal loss of effective ingredients in the materials.
Characteristics of Tunnel Microwave Drying Machine:
1. Easy to control, clean and hygienic, selective heating, safe and non-toxic. The sterilization effect of microwave on food, agricultural products, medicinal herbs cannot be achieved by other drying methods.
2. Energy saving and efficient: Different materials have different absorption rates for microwaves, and substances containing moisture are prone to absorbing microwave energy. The ambient temperature in the workplace will not increase as a result, and the production environment will be significantly improved. According to a large amount of data, compared with other methods such as electric heating and infrared heating, microwave heating and microwave drying have high efficiency and energy savings.
3. The materials dried and processed by microwave dryers can significantly improve their nutritional content, color, and added value, while also increasing their selling price. Therefore, choosing a microwave dryer with higher cost-effectiveness will also bring greater benefits to the processing enterprise itself.
